The New NATO Faultline

NATO is entering a new phase marked by an emerging two-tier deterrence structure, where frontline states accelerate national and regional defence efforts while core powers adopt a more cautious, diplomacy-oriented posture. The executive summary explains how this asymmetry is blurring collective red lines, complicating crisis decision-making, and creating capability gaps that adversaries may exploit.

This report traces the origins of the divide, from Russia’s actions in Ukraine to rising defence spending across Europe and growing doubts about the permanence of U.S. security guarantees. It examines the contrasting strategies of frontline states such as Poland and the Baltic countries, core capability anchors like the United States, Germany, France, and the United Kingdom, and peripheral members prioritizing diplomatic restraint. Scenario-based projections outline possible futures—from deeper integration and burden-sharing to institutionalized bifurcation and weakened alliance coherence.

With implications for deterrence credibility, defence procurement, industrial coordination, and transatlantic strategy, this briefing provides a forward-looking perspective on NATO’s internal dynamics. For policymakers, defence firms, and strategic planners, overlooking these fractures could mean misreading the next phase of European security.
